(build and coverage are for latest repo code, package and downloads are for PyPI release)
- Frontend: Dynamic DNS updates via dyndns2 protocol (like supported by many DSL/cable routers and client software).
- Backends:
- Uses Dynamic DNS UPDATE protocol (RFC 2136) to update compatible nameservers like BIND, PowerDNS and others (the nameserver itself is not included).
- Optionally uses the dyndns2 protocol to update other services - we can send updates to configurable third-party services when we receive an update from the router / update client.
- Prominently shows visitor's IP addresses (v4 and v6) on main view, shows reverse DNS lookup results (on host overview view).
- Multiple Hosts per user (using separate secrets for security)
- Add own domains / nameservers (public or only for yourself)
- Related Hosts: support updating DNS records of other hosts in same LAN by a single updater (e.g. for IPv6 with changing prefix, IPv4 also works)
- Login with local or remote accounts (Google, GitHub, Bitbucket, ... accounts - everything supported by the python-social-auth package)
- Manual IP updates via web interface
- Browser-based update client for temporary/adhoc usage
- Shows time since last update via API, whether it used TLS or not
- Shows IP v4 and v6 addresses (from master nameserver records)
- Shows client / server fault counters, available and abuse flags
- Supports IP v4 and v6, TLS.
- Easy and simple web interface, it tries to actively help to configure routers / update clients / nameservers.
- Made with security and privacy in mind
- No nagging, no spamming, no ads - trying not to annoy users
- Free and open source software, made with Python and Django
